Pastoral production and use of forest rangelands in Western Rif

Abstract

Extensive livestock farming plays an important socio-economic role for goat farmers in Western Rif. Silvopastoral resources are the main source of feed for herds. Actually, these resources have a strong tendency to degradation. To ensure their sustainability, setting up a monitoring and evaluation system is a necessity. The aim of this study was to assess the pastoral production and the silvopastoral areas use. This work was carried out in two forest rangelands (Ain Rami and Derdara), where dairy goat farming has been dominant for decades. For the floristic study, a total of ninety-six plant species were counted. The chemical composition and nutritional value of pastoral species varied according to the analyzed species. For phytomass, significant differences were noted according to the season and the sites, with a maximum productivity in spring of 2725 and 2465 kg DM per hectare, respectively in Ain Rami and Derdara. The degree of palatability depended mainly on the chemical composition and the season of pastoral species intake. The most grazed rangelands were overgrown by unpalatable species. Management actions of silvopastoral resources use, including a reduction of grazing pressure, should be developed to ensure the productivity and the sustainability of these resources.
